Bhikkhus, if you develop and make much this one thing, it invariably leads to weariness, cessation, appeasement, realization and extinction. What is it? It is recollecting the Enlightened One. If this single thing is recollected and made much, it invariably leads to weariness, cessation, appeasement, realization and extinction.Anguttara-Nikaya: Ekanipata: Ekadhammapali: PañhamavaggaVSMVMMWBBTBHTWTBTMy Page

I have heard that at one time the Blessed One was staying in Savatthi at Jeta's Grove, Anathapindika's monastery. Then a certain deva, in the far extreme of the night, her extreme radiance lighting up the entirety of Jeta's Grove, approached the Blessed One. On approaching, having bowed down to the Blessed One, she stood to one side. As she stood to one side, she addressed him with a verse.
